Cartographic and Topographic Mapping of the Icy Satellites of the Outer Solar System
نویسنده
چکیده
Cartographic and topographic mapping of the major satellites of the Outer Solar System has been in progress since the late 1980’s, beginning with Voyager image data, and incorporating Galileo and recently Cassini imaging data as released to the public. Global image mosaics, based on cartographic control nets, have been produced for all these satellites. In addition, digital topographic maps have been produced for restricted areas on the Galilean, Uranian satellites, and Triton. Global topographic maps as well as limited high resolution topographic samples have been produced for the Saturnian satellites. These data have been used to investigate the properties of the icy outer layers (esp. Europa and Io), discrimination between competing hypotheses of geologic origins (on Triton, Ganymede, Europa, and Enceladus for example), and in some cases the thermal histories of these bodies (esp. Ganymede and Dione). These data are available on request for use in mapping and modelling of geologic and geophysical processes.

Large Impact Features on Saturn's Middle-sized Icy Satellites: Global Image Mosaics and Topography
Introduction: With the approach of Cassini to the Saturn system, attention naturally focuses on the planet, its rings and Titan, but the Saturn system is also populated by a number of smaller satellites. The seven middle-sized icy satellites, along with those of Uranus, (between 400 and 1500 km wide) are distinctly different geophysically and geologically from their much larger Galilean-class b...
متن کاملGeneration of Digital Topographic Maps of Planetary Bodies
In recent years, the exploration of the solar system was intensified. Several space missions have been planned, launched, or are in operation yet. Some of them are supplied with modern camera experiments: the High Resolution Stereo Camera (HRSC) on Mars Express or the Cassini Imaging Science SubSystem (ISS). Especially HRSC data are well suited to derive Digital Terrain Models and color orthoim...
متن کاملConstraints from deuterium on the formation of icy bodies in the Jovian system and beyond
We consider the role of deuterium as a potential marker of location and ambient conditions during the formation of small bodies in our Solar system. We concentrate in particular on the formation of the regular icy satellites of Jupiter and the other giant planets, but include a discussion of the implications for the Trojan asteroids and the irregular satellites. We examine in detail the formati...
متن کاملTectonics of the outer planet satellites
Tectonic features on the satellites of the outer planets range from the familiar, such as clearly recognizable graben on many satellites, to the bizarre, such as the ubiquitous double ridges on Europa, the twisting sets of ridges on Triton, or the isolated giant mountains rising from Io’s surface. All of the large and middle-sized outer planet satellites except Io are dominated by water ice nea...
متن کاملMulti-wavelength Photometry of the Icy Saturnian Satellites: a First Look
Introduction: The light reflected from planetary surfaces and measured by remote sensing instruments is affected not only by the composition of the surface but by the physical structure of the surface. The structure of the surface is characterized by both endogenic and exogenic processes. We investigate the effects of these processes on the surfaces of the icy Saturnian satellites using photome...
